Applies to: Cortex-A5, Cortex-A9, RealView Development Suite (RVDS)

Answer

This knowledge article provides example initialization code for the Cortex-A9 MPCore and Cortex-A5 MPCore.  The example implements a simple bare metal SMP program, and demonstrates how to enable and configure the MPCore's hardware features.

The example includes code for configuring the Interrupt Controller, SCU, MMU, caches, and branch predictor.

Requirements

The intention of this example is to be readable and easy to follow, not provide optimal performance. The example is not modelled on an operating system, and does not use threads.

This example can be run on:
